Problems solved by technology

[0002] At present, there are many problems in the development and application of foliar sprays: first, most of the foliar sprays focus on macronutrients or microelements, and cannot organically combine large, medium, and microelements, so that the ratio of nutrients among the three is the same as that of micronutrients. Crop demand matching; second, single function
Most of the foliar sprays only provide mineral nutrients for crops. Although regulators are added to some sprays, they may pose a threat to food safety production. Natural and non-toxic stress-resistant regulators and mineral nutrients are rarely used. combine
Third, the efficacy characteristics are generally not strong
Nutrient formulations of many foliar sprays do not match the differences in nutrient requirements of target crops, resulting in ineffective application
In particular, there is a lack of products aimed at preserving cotton bolls and promoting the formation of large bolls; fourth, the product quality is unstable, many products have a short storage period, and are prone to dilution and precipitation. It is difficult to guarantee the active ingredients, and the application effect is not good
Although there are many types of spraying agents on the market, few of good quality, the price of most products does not match the technical content, resulting in some "false" foliar spraying pits and harmful to farmers.

[0009] Embodiment 1 (1) the preparation of compound auxiliary agent. Mix 100 parts of triethanolamine and 80 parts of glycerin, add 20 parts of OP-10 into the mixture, stir, and prepare compound additives. (2) Weigh 100Kg disodium EDTA and dissolve it in 250L of water at 70-80°C, and dissolve it in FeSO in turn 4 ·7H 2 O 80Kg, MnCl 2 ·6H 2 O 100Kg, CuSO 4 ·5H 2 O 10Kg, ZnSO 4 ·7H 2 O 100Kg; citric acid 150Kg, polyphosphoric acid 50Kg, prepared as solution A. (3) Dissolve 50Kg of borax in 100L of water at 70-80°C, then add liquid A, stir, and then add MgCl in turn 2 ·4H2O 50Kg, urea 100Kg, KNO 3 100Kg to obtain liquid B. (4) Add 50L content of 2-4% nitrofulvic acid solution 50-100L / m3, proline 20Kg, and compound auxiliary agent 50L in B liquid, and adjust the pH value to 3-3.5 with ammonia water, then water Set the volume to 1000L. The liquid is a special foliar spray for stress-resistant boll-preserving cotton.

Embodiment 2

[0010] Embodiment 2 (1) the preparation of compound auxiliary agent. Mix 120 parts of triethanolamine and 40 parts of glycerin, add 40 parts of OP-10 into the mixture, stir, and prepare compound additives. (2) Weigh 50Kg disodium EDTA and dissolve it in 250L water at 70-80°C, and dissolve it in FeSO in turn 4 ·7H 2 O 120Kg, MnCl 2 ·6H 2 O 50Kg, CuSO 4 ·5H 2 O 5Kg, ZnSO 4 ·7H 2 O 120Kg; citric acid 100Kg, malic acid 20Kg, polyphosphoric acid 30Kg, prepared as solution A. (3) Dissolve 30Kg of borax in 100L of water at 70-80°C, then add liquid A, stir, and then add MgCl in turn 2 4H 2 O80Kg, urea 80Kg, KNO 3 80Kg, obtain B liquid. (4) Add 80L of nitrofulvic acid solution with a content of 2-4% and 50L of compound additives to liquid B, adjust the pH value to 3-3.5 with ammonia water, and then dilute to 1000L with water. The liquid is a special foliar spray for stress-resistant boll-preserving cotton.

Embodiment 3

[0011] Embodiment 3 (1) the preparation of compound auxiliary agent. Mix 40 parts of triethanolamine and 60 parts of glycerin, add 100 parts of OP-10 into the mixture, stir, and prepare compound additives. (2) Weigh 80Kg disodium EDTA and dissolve it in 250L water at 70-80°C, and dissolve it in FeSO in turn 4 ·7H 2 O 50Kg, MnCl 2 ·6H 2 O 150Kg, CuSO 4 ·5H 2 O 10Kg, ZnSO 4 ·7H 2 O 50Kg; malic acid 70Kg, polyphosphoric acid 30Kg, prepared as solution A. (3) Dissolve 60Kg of borax in 150L of water at 70-80°C, then add liquid A, stir, and then add MgCl in turn 2 4H 2 O30Kg, urea 180Kg, KNO 3 50Kg to obtain liquid B. (4) Add 30Kg of proline and 50L of compound additives to liquid B, adjust the pH value to 3-3.5 with ammonia water, and then adjust the volume to 1000L with water.
